THlL L-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 332,843, dated December 22, 1885.

Application filed November 5, 1885. Serial No. 181,896. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. SIMPSON, a citizen of the United States, residing at Maltaville, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Thill-Oouplings, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to anti-rattlers for thin-couplings; and the object in View is to provide a device to be inserted between the clip and shank-iron of a shaft, whereby wear may be taken up and rattling prevented, and it is desired to provide an article complete in itself and capable of being applied to any vehicle without change of construction of the parts, and so made as to retain itself in operative position when detached.

Referring to the drawings, Figure 1 is a central vertical longitudinal section of a wagonaXle provided with my anti-rattler, and Figs. 2, 3, and 4. are details showing the detached device in different positions.

Like letters of reference indicate like parts in all the figures.

A represents the axle of a vehicle, which is provided with the usual clip, 13, mounted thereon, and secured thereto by means of a suitable tie-bar and bolts, A A", respectively, and which is provided with the well-known brackets or cars, perforated for the reception of the bolt O,which connects the shank-iron D thereto.

E represents a rubber cushion, which is concave at its front edge, as at E, to adapt the same to fit over the cylindrical portion of the shank-iron of a shaft, and which is tapered from top to bottom, as clearly shown at E,

Fig. 4, for a purpose hereinafter specified,

The back of the cushion is formed with a vertically-tapering groove, E, for the reception of a screw-threaded stud or rod, F, the lower end of which is bent, as at F, at a right angle to its body portion, thus forming a seat or head for said cushion E.

As shown in Fig. 1, the stud or rod F is tapered from bottom to top, adapted to fit the groove E in the cushion E, and is provided at its top with a thumb-nut, F adapted to be screwed thereon.

Interposed betweed the thumb-screw F and the cushion E is a plate, G. bent to form a right angle, and extending down in rear of said cushion, as at G, and resting upon the rear flat surface of the bolt F, whereby a metal bearing-surface exists between the bolt and the plate. It will thus be seen that by reason of the taper in the cushion E the device as a wholeis adapted to be inserted into the space between the clip and shank-iron of any ordinary shaft, and that said device may be manufaetured and sold separately, to be afterward inserted for use. It will also be seen that as the rubber portion E becomes worn, by reason of the constant wear occasioned by the shank-iron, the same may be readily tightened and bound to said shank-iron by means of the stud F and nut F, the operation being simply to insert a pin in the eye F of said nut, and turn the same, which draws upon the plate; and in connection with the tapered rod or stud the rubber is pressed tightly against said iron, the plate G beingdepressed and bearing against the clip B at one side and against the fiat back of the bolt F at the other side, thus giving a metal bearing, which is formed to offer a minimum resistance to the downward movement of the'plate.

It will be noticed that the rubber cushion'E is thicker at the upper end of its concave face than at the lower. The purpose of this construction will be apparent when it is stated that the lower thinner edge of the cushion,interposed between the seat F on the bolt and the shank-iron D, serves to practically prevent any upward movement of said seat F, so that the entire compression of the cushion takes place from above, by reason of the depression of the plate G, and of the said sub- 9c stantial lack of motion upon the part of the seat F.

The device is exceedingly simple, compact, and durable, and can be manufactured at a nominal cost, there being no need whatever of 5 any special fitting to adapt the same to any ordinary thill.

Having described my invention and its operation, what I claim, and desire to secure by Letters Patent, is

1. An anti-rattler to be inserted between the clip and shank-iron of a shaft, consisting IOO of a rubber cushion, as E, concaved, as at E, and provided with a tapering groove, as E, and having a tapered stud or rod, as F, bent to form a seat or head, as F, for said cushion, 5 and provided with a bearing-plate, as G, ar-

ranged to slide upon the back of the bolt, and a thumbscrew, F substantially as shown and described.

2. The combination of the cushion E, ta- :0 pered, as at E and concaved, as at E, provided with the tapering groove Eiand having the stud or rod Ebent to form a seat or head, F, the plate G,bent, as at G, and the thumbnut Fflwith the shank-iron D and clip A, sub- 15 stantially as shown and described.
